Will Hayden, who appears on the Discovery Channel reality series Sons of Guns, was arrested Saturday for allegedly molesting a child.

He is accused of both the molestation of a child and a crime against nature, East Baton Rouge Sheriff's website says, according to TMZ, who first learned of the arrest. Hayden was freed a day later after he posted a $150,000 bond.

The reality star says that the claims came from his ex-girlfriend, who is the mother of the girl Hayden allegedly abused. He believes that the claims are just an attempt to get back at Hayden for moving on without her.

Hayden is currently married to another woman with whom he is raising the ex-girlfriend's daughter with. She was interviewed by Child Protective Services and was then allowed to return home. "There was never any impropriety in our home," his older daughter Stephanie told the site. "He was and is a good father."

According to FOX411, Hayden's lawyer Frank Holthaus said, "I believe [the allegations] are completely false."
